To all whom it may concern: 7

Be it known that 1, WILLIAM W. WATSON, a citizen of the'United'States, residing at Jamestown, county of Chautauqua, and have invented new and useful Improvements in lVindow-Sashes, of which the following, taken in connection with the accompanying drawing, is a full,

clear, and exact description.

' The invention relates to window sashes and refers particularly to the means for removably attaching the glass to the window sash, without the use of nails, putty or similar devices that are usually resorted to for attaching the glass to the sash; and the invention consists in the arrangement and construction of the parts, as shown in this specification and drawings and pointed out in the claims.

In the drawings, Figure 1 is a crosswise sectional view of the Window sash, one side showing the glass firmly attached to the -frameside, and the other side showing the glass in process of attachment. Fig. 2 1s a sectional view of the frame side without the attaching strips. Fig. 3 is a crosswise sectional view of the resilient slotted tube for locking the parts together in attaching the glass to the frame side; and Fig. 4 is a crosswise sectional view of the additional lock strip which is held in place by the resilient tube. Fig. 5 is a perspective view of a portion of the windowframe showing the manner of attaching the glass to the sash. Fig. 6 is a sectional view of a modification of the frame construction showing a solid frame side and filling strip in combination with a movable holding strip for the glass.

Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the preferred form of the frame side as cut and bent from the flat sheet metalstrips by means of suitable dies and presses into the flat tubular form, which is formed also with the curved edge 11. The two edges ofthe sheet metal fitrip are preferably extended horizontally from the lower side of the tubular frame 10 in the flange 12 and firmly united together,

the lower edge of the sheet metal extending up over the upper edge and extending inward in the horizontal flange 13 which is spaced from the upper side of the united edges of the sheet metal so as to receive the flat flange of a sheet metal holding strip 14 Specification of Letters Patent.

under said flange 13. The two thicknesses of the sheet metal throughout the portion 12 combined with the locking flange 13 forms this portion into a strong, rigid holding flange, which also stiifens and greatly strengthens the entire tubular frame side 10.

A holding strip 14 is provided, preferably made of sheet metal and having a flange 15 which fits beneath flange 13. The side 16 is preferably curved in the opposite direction from side 11 of frame side 10, the opposite curves being so formed as to cause the groove, formed by'the placing of the :curved sides 11 and 16 opposite one another, to enlarge inwardly. The other edge of the 15 is formed in a tubular part 17, which is of sufficient size to form the space or groove 18 between said tubular part 17 and flange 13 when flange 15 is inserted beneath the same, as shown in Figs. 1 and 5. \Vhen made of sheet metal it is apparent that holding strip 14 is resilient. That i s,'it will spring or give slightly both in receiving the glass and also in locking the holding strip in place.

The edge of the glass 19 is inserted in the groove 18 formed between the tubular part 17 and the flange 13. 111 order to protect the edge of the glass, a suitable packing or protection 20 is provided around the edge of the glass, which with the resilient holding strip 14 firmly yet resiliently holds the glass in place.

A filling or forthe groove formed between the sides 11 and 16 in order to press the holding strip 11 out into place. Filling strip 21 1s preferably made in a hollow tubular form and slotted along one side so as to give great resilience to the tubular filling strip, thereby aiding in the resilient holding of the parts in place.

It. is a )parent that the movable holding strip 14 y means of its form makes two grooves, that is, a groove 18 within which the protected edge of the glass 19 is inserted, and on the opposite slde of the holding strip 14 the groove enlarged inwardly formed by the sides 11 and locking strip 21 is provided It is thus apparent parting window attached thereto to form the flange 13.

silience of the, holding strip 14 the filling.

strip may often be made solid as shown at 21 in Fig. 6. The tubular sheet metal form of frame side is preferred but the solid frame side would serve a good purpose for some forms of cheap sash. construction. It is also obvious that this method of attachment may be applied to panels and other materials than window glass without defrom my-invention.

I cla m as new: p 1 In a window sash, the combination of the frame having a groove lengthwise of the frame side, a movable side for said groove adapted to receive the edge of the glass, and a filling strip for said groove. g

2. In a window sash' the combination of a frame having a groove lengthwise of the frame side, the inner side of said groove movably attached to the frame side and adapted to form a second groove to receive the edge of the glass, and a filling strip for the first groove.

3. In a window sash, the combination of the frame having two grooves, one of'said grooves adapted to'receive the edge of the glass and the other groove enlarged inwardly, and a filling strip for said enlarged groove.

4. In a window sash, the combination of I j the frame, a movable holding strip on said frame, said holding strip adapted to form a groove on each side thereof with said frame, one of said grooves adapted to receive the edge of the glass, and a resilient filling strip adapted to be inserted in the other groove to hold the parts in place.

5. In a window sash, the combination of the frame with groove enlarged inwardly, a

side of said groove movable, said movable side adapted to receive the edge of the glass, and a resilient tube forming a filling piece adapted to be inserted in said groove.

6.'In a Window sash, the combination of the frame havin a groove contracted at the mouth, a side 0? said groove removably at-v tached to said frame, said removable side adapted to receive the edge of the glass, and a resilient slotted tube adapted to be inserted in said groove to form a locking strip for said parts.

7. In a window sash the combination of the frame, a flange on the edge of said frame, a holding strip having a flange to engage the flanged edge of said frame, said holding strip adapted to receive the edge of the glass with sai flanged frame, said holding strip and frame adapted to form a groove enlarged inwardly therebetween, and a slotted tubular lock strip adapted to be inserted in said groove.

8. In a window sash, the combination of a tubular metal frame bent from the flat sheet metal strip, the edges of said strip united and extended from a flange, a holding strip adapted to engage said flange and form a groove enlarged inwardly along said tubular frame, said holding strip and flange adapted to receive the protected edge of the glass therebetwfeen, and a slotted tubular locking strip adapted to be inserted in said groove,substantially as and. for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
